Problems with mailing list

[Norbert Irmer <norbert.irmer@heim9.tu-clausthal.de>]

Hi Rick,

I noticed a strange thing, not all mails of the rte-crossfire mailing
list are forwarded to me !

For example I didn't got the reply of Jan Echternach to my mail of today
(and another mail from him too) :

my mail:

  Re: [CF:1329] Pocket realities eat stuff? 
           From: Norbert Irmer <norbert.irmer@heim9.tu-clausthal.de>

not received mails from Jan Echternach:

  Re: [CF:1329] Pocket realities eat stuff? 
           From: Jan Echternach <echter@informatik.uni-rostock.de>

  Re: dublication bug & server crashes (RE) 
           From: Jan Echternach <echter@informatik.uni-rostock.de>

But his mails appear in the rte mailing list archive, so I don't
understand this. 

Can you help ?

Norbert
